lscpu: add Hypervisor detection
|
||||
|
||||
This patch adds two new fields:
|
||||
|
||||
* "Hypervisor vendor" -- based on CPUID and hypervisor specific
|
||||
PCI devices. lscpu(1) supports KVM, XEN, Microsoft HV now.
|
||||
|
||||
* "Virtualization type"
|
||||
- "none" = Xen dom0
|
||||
- "full" = full virtualization (KVM, Xen, ...)
|
||||
- "para" = Xen paravirtualization

|
||||
|
||||
The (untested) patch below introduces a new fields "Hypervisor vendor
|
||||
ID:" and "Para-Virtualized:" in lscpu(1).
|
||||
|
||||
The "Hypervisor vendor ID:" field reports the raw ID, it means it works
|
||||
for all hypervisors (the same logic like CPU "Vendor ID:").
|
||||
|
||||
I think this solution is a good compromise to avoid a new tool.
|
||||
|
||||
(Note that lscpu(1) does not support XEN dom0 now. This problem will
|
||||
be resolved ASAP.)
